Back in early January we posted our suggestions for the best adventure travel destinations for 2011, with places like Ethiopia, Croatia, and Guyana all earning a nod. While we gave plenty of praise to those exotic locales, we also gave a big tip of the hat to the good ole’ U.S. of A. as well. We went on to espouse the virtues of adventure travel right here at home, which includes not only plenty of great destinations but also the ability to visit them without breaking the bank in the process.

So, whether you’re into climbing mountains, hiking trails, or paddling whitewater, here are five great domestic adventure destinations guaranteed to fill your need for an adrenaline rush and help you conquer that wanderlust in the process.

Michigan’s Upper Peninsula
It may be hard to believe, but the state of Michigan is actually home to a spectacular wilderness area that has a lot to offer the adventure traveler. The Upper Peninsula, or “U.P.” as it is known, is the perfect setting for outdoor enthusiasts year round. There are hundreds of miles of trails to be hiked or biked in the warmer months and during the winter they serve as excellent cross country skiing or dog sledding routes as well. Paddlers will enjoy the Lake Superior coastline, which offers an experience not unlike sea kayaking, while campers and backpackers will appreciate the dense, but beautiful, state and national forests that are found throughout the area. Wildlife is in abundance as well, with black bear, deer, wolves, coyotes, and many other creatures inhabiting the wilderness as well. Perhaps the best reason to visit the U.P. however is for the solitude. The peninsula makes up about 1/3 of the entire size of the state of Michigan, but only about 3% of the state’s total population actually lives there, which means there are plenty of wild spaces and few people to bump into on the trail.Yosemite National Park, California
One of the most spectacular outdoor playgrounds in the entire world is located right in central California. Yosemite National Park is well known for its spectacular scenery that features towering granite cliffs, sparkling clear waterfalls and streams, and thick forests that include groves of Sequoia trees. The park has more than 750 miles of hiking trails alone and whitewater rafting along the Merced River is also a popular summer time activity. In the winter months skiing, both downhill and cross country, are permitted within the parks boundaries, and snowshoeing is a fantastic way to explore the wilderness as well. Yosemite also happens to be home to some of the best rock climbing in the world, with the legendary El Capitan drawing climbers from across the planet. That rock face isn’t for beginners however, and if you’d prefer an easier way to the top, you might want to consider hiking up Half Dome, another one of the parks major attractions, instead.

Grand Tetons National Park, Wyoming
Often overshadowed by other national parks in the area, Wyoming’s Grand Tetons National Park is a spectacular destination in its own right. With more than 200 miles of hiking trails, it is an ideal destination for backpackers. But less experienced hikers beware, due to its combination of remote backcountry and altitude, it can be a challenging place to explore. The park also happens to be bisected by the Snake River, which provides world-class fly fishing opportunities and easy kayaking as well. Mountaineers love the remote nature of the Teton Mountains, which afford them real opportunities to test their alpine skills on any number of challenging peaks, including the 13,770-foot Grand Teton itself. The park has plenty to offer wildlife spotters too. While visiting, keep your eyes peeled for moose, grizzly bear, wolves, coyotes and much much more.

Maine’s North Woods
For considerably easier, but no less satisfying, mountains to climb, look no further than Maine’s North Woods. The region is a dramatic, and mostly untouched, wilderness that is a fantastic destination for hikers and backwoods campers, offering thick forests and plenty of low altitude (read 2000-3000 feet) peaks to bag. As you can imagine, wildlife is in abundance here as well, with moose and black bear making regular appearances, along with otter, deer, and even bobcats. Paddlers can choose to enjoy a serene day in a canoe on one of the many lakes that dot the area or elect to head over to Maine’s Atlantic Coast for a decidedly different, and more challenging, experience in a sea kayak. With over 3.5 million acres of forest spread out across northern Maine, there is plenty of backcountry to explore.

Taos, New Mexico
Located in New Mexico’s Sangre de Cristo Mountain region, Taos is one of those towns that sits at the epicenter of an outdoor enthusiasts’ paradise. In the winter, it is one of the best ski and snowboard destinations in the entire country, and the miles of local trails are fantastic to explore while snowshoeing as well. During the summer, those same trails make Taos a world-class mountain biking destination and rock climbers will love the variety of challenges they find in the nearby mountains too. The warmer weather also brings excellent whitewater rafting, as well as fantastic opportunities for horseback riding, hiking, and trail running through a pristine wilderness that never fails to surprise visitors with its beauty and wonder. The village of Taos is a great destination in its own right, enchanting travelers with its down home charm, and it serves as a prefect base camp for those who come to play in the backcountry.

There you have it. Five great domestic destinations to that will give you plenty to see and do no matter what time of the year you visit. It’s still plenty early in 2011 to start planning your own escape to one of these outdoor paradises.
